The answer to your question would be: Because 4 + (-7) is an equivalent expression, your answer is -3. The reason for this can be described using integers. So lets say you have $4. You owe your brother $7. Since you don't have enough to pay him, you can pay him all your money, but you still have to pay him $3 more. This means technically your balance is $-3, cause if he needs the money, the second you get it he will ask for it. Sorry if this isn't too great of an example, not sure what else I could think of. Pretty much remember when subtracting a number, you can add the negative of the number, because that is the same thing. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer (Not necessarily mine). Thanks, it really helps! :D
